Snell's law relation for air glass boundary is given by equation n_(air) sin theta_(1) = n_(glass) sin theta_(r) . Here angle of refraction in glass is theta_(r) and the angle of incident in air is theta_(i) . The refractive index of air is n_(air)=1 (with negligible uncertainty). In an experiment to verify Snell's the best fit line on a graph between sin theta_(r) (on the y-axis) and sin theta_(i) (on the x-axis) is given by the eqyuation y=(6.66pm0.05)xx10^(-1)x+(0.022pm0.024) . The refractive index of the glass, including the error is reported as 1.abpm 0.0c , where a,b and c are digits after tje decimal point. Calculate value of (a+b-c) .

A ball is dropped from a height of 20 m above the surface of water in a lake. The refractive index of water is 4.3. A fish inside the lake, in the line of fall of the ball, is looking at the ball. At an instant, when the ball is 12.8 m above the water surface, the fish sees the speed of the ball as [Take _(g)=10m/s^(2).]

A horizontal cylinderical tank (6)/(pi)m in diameter is half full of water. The space above the water is filled with a pressurized gas of unknown refractive index. A small laser can move along the curved bottom of the water and aims a light beam towards the centre of the water surface. When the laser has moved a distance s=1m or more (measured from curved face) from the lowest point in water, no light enters the gas. The refractive index of gas is (mu_("water") = 4//3)
